C: When using ML cloth material as a backing material, etc., spun yarn, woven fabric, non-woven material, etc. made of this fiber mixture is impregnated with polyfluoroethylene such as PT "F". In addition, when covering the composition of the spun yarn of the above-mentioned fibers 1 and 4 into a composition such as I71, it is necessary to pre-impregnate [] [-'13] before braiding without yarn breakage etc. It can be easily carried out, and the product is dense and movable (1!7%).

に至ったものである。However, impregnation of TFI-E is usually done with water! , 1. Where 1j is done using Mulsion,
Flame-resistant fibers or carbon fibers have poor affinity with aqueous emulsions, and these 48 Ml spun yarns may have a surface treatment agent attached to them. It was difficult to avoid sufficient penetration of C' into the interior. The present inventors investigated a technique for sufficiently permeating PTF E I multicon into such fiber materials and effectively impregnating them with PTF IE. Flame-resistant fiber or carbon 1 coated with soda in advance! It was discovered that by impregnating a TFE emulsion into an aggregate of miscellaneous materials and then drying it, an aggregate of flame-resistant fibers or carbon fibers can be effectively impregnated with PTFF, leading to the present invention.
